Meh, s'ok. Port Royale II is a better trading game, Pirates is more of an arcade game. Lots of quests but really it gets old fast once you beat it once. Lack of variety, no multi player and massive repetition are it's weak points. That being said it is still fun. Sid Meir makes the interface simplicity itself the graphics are great and the sword fighting is fun but the same scenes over and over again make it dull. Check out
Pirates of the Burning Sea if you want a cool looking multi player pirate sim.
